Abstract
L'invention a pour objet un procédé de préparation du protoxyde d'azote par dissociation thermique du nitrate d'ammonium dans une solution de sel ou un bain de sel à plusieurs composants. Elle est caractérisée en ce que ce procédé consiste à mélanger 1 partie de nitrate d'ammonium et 5 parties d'une solution de sel concentrée ou d'un bain de sel fondu, à maintenir le mélange ainsi obtenu à une température comprise entre 200 degrés C et 240 degrés C, au moins un des composants de solution ou du bain fondu étant un acide minéral, un anhydride d'acide ou un sel acide d'un acide minéral. Elle concerne la préparation du protoxyde d'azote.The subject of the invention is a process for the preparation of nitrous oxide by thermal dissociation of ammonium nitrate in a salt solution or a multi-component salt bath. It is characterized in that this process consists in mixing 1 part of ammonium nitrate and 5 parts of a concentrated salt solution or of a molten salt bath, in maintaining the mixture thus obtained at a temperature of between 200 degrees C and 240 degrees C, at least one of the components of the solution or the molten bath being a mineral acid, an acid anhydride or an acid salt of a mineral acid. It relates to the preparation of nitrous oxide.
